Bretonnia lies to the southwest of the Empire, between the Grey Mountains and the Middle Sea. To its south lies the vast Forest of Loren, home to the only permanent communities of Elves left in the Old World. The Bretonnians are ruled by a king whose castle rises high into the air in imitation of the ancient, abandoned Elf towers along the northern coast, though it is in a constant state of repair like much of the country.

All Bretonnian Knights are raised to practice their noble code of chivalry, which demands not only the highest standards of conduct, combat skills, and horsemanship, but also states that Knights fight to honour their lords and destroy the enemies of Bretonnia. The Knights of Bretonnia are perhaps the most daring warriors in the Old World, and they form the core of their army.

The Knights are supported by small bodies of Men-at-Arms, crudely equipped by the Knights.
